Deleted member 1618 used the bedding fabric that you lay down in the garden, in order to prevent weeds from growing. I typically remove it once a year, as part of my annual clean-up and shake it out; it keep heavy rain and such from the cable harness and such.
Also, I use No Ox as in "No Oxidation" grease on the fuse spades and the exposed test point on the top of the fuse; this will also prevent Oxidation or corrosion.
In addition, I also coat the big electrical connectors on the battery terminals with NO OX, and a dialetric grease around the perimeter of the Reverse Module and the exposed electrical connectors.
All of these items are good to check at least once a year and clean them up if looking corroded; I use a plastic toothbrush, you don't want to use a metal brush unless you remove the Ground lead on the battery's [Negative ( - )] terminal.
Deleted member 1618 is a jerk BTW...
